Light Measurement Systems

International Light Technologies (ILT) has been a leader in developing light measurement systems for over 50 years.  Since we introduced the first light meter in 1965, our team of mechanical, electrical, and optical engineers have delivered accurate and reliable light measurement systems that are trusted by organizations of all types and sizes.  

 

Starting in 2015 an entire new suite of upgraded products, with new features, capabilities, and design, has been released.  These products incorporate the latest technology including touch screen displays, internal data storage, rechargeable batteries, Wi-Fi compatibility, user-friendly software apps, and more.

  • ILT2400
  • ILT750 Bili Light Meter
  • ILT800 Belt Radiometer
  • ILT350 Chroma Meter
  • ILT960 Miniature Spectrometer Series
What We Offer

We offer an array of light measurement products and devices including light meters, UV light meters, radiometers, spectrophotometers, and spectroradiometers, in addition to supporting accessories including, detectors, filters, input optics, integrating spheres and calibrations. We engineer our products to withstand the many harsh applications required from underwater applications to direct exposure to high levels of UV, to last years of use.

Quality Engineering

ILT's Calibration Lab offers both NIST traceable and ISO17025 accredited light meter calibrations. Each of our meters comes with an ISO17025 Accredited Calibration Certificate.  All ILT light measurement products are manufactured using the guidelines, practices and procedures that conform to ISO9001. (ISO9001:2015 pending for 2017).  ILT is also ISO13485:2016 certified.

Customization Provided

Looking for a customized solution?  Our technical staff works directly with our customers, both in large and small volumes, to offer customized light measurement solutions, often designed from off-the-shelf components, for rapid product design and delivery. Most ILT products are available in OEM and private label, with both custom and standard configurations.  Visit our Core Competencies page to see a full list of ILT's capabilities.

Calibrated Light Measurement

ILT knows that measurement is a critical step in validating any process where light is used – from medical, to industrial, to scientific to manufacturing applications and more. If delivered in the wrong dose, e.g., too much or too little, the entire process can be rendered ineffective. Depending upon the process, this breakdown can have dire consequences including product failures, personal injury and/or increased production costs. Our sales team is trained to help customers select the right equipment to meet their measurement and monitoring needs and ensure accurate light levels are confirmed.

Introducing The ILT750 Bili Light Meter
Watch

Definitely not your average bili light meter, the ILT750 makes validating blue light sources from neonatal jaundice treatment systems quick and easy.  No time-consuming point-by-point measurements.  No adding.  No calculating.  Just fast, accurate measurement results you can trust.

What is ISO17025 Accredited and NIST Traceable Calibration?

One of the most important features of any light meter is its calibration.  What sets quality meters apart from the rest is a combination of the quality of the components, and the quality of the calibration that ensures the conversion from volts or amps to the equivalent light level reading such was watts or joules, is accurate.  Without an accurate calibration the readout is simply a relative value, and the units on the meter may as well list volts, amps, relative, or percent.  Accurate, accredited, traceable calibration means the readings on the display have value.  This article highlights what each of these separate and unique standards are, and why they are important.
